Detector performance at SHiP for cascade-produced long-lived particles / Climescu, Matei (Gent U.) ; Kyselov, Yehor (Taras Shevchenko U.) ; Ovchynnikov, Maksym (CERN)
Previous studies have shown that cascade production in the thick target of the SHiP experiment may substantially enhance the number of light long-lived particles (LLPs) decaying in the fiducial volume. [...]

BPS Non-Renormalization in the BMN Matrix Model / Colin-Ellerin, Sean (CERN) ; Papadodimas, Kyriakos (CERN)
We show in the $(0+1)$-dimensional Berenstein-Maldacena-Nastase matrix model, dual to M-theory on a pp-wave background, that the coupling can be changed between any two finite, non-zero values using a special class of deformations, known as conjugation deformations. [...]

The production of a top-antitop quark pair in association with a $W$ boson constitutes one of the heaviest final states currently studied at the Large Hadron Collider (LHC) at CERN. [...]

Closing the loop on $Φ^4$ in AdS$_3$ / Carmi, Dean (Haifa U. ; CERN) ; Ciccone, Riccardo (Haifa U. ; CERN) ; Sukholuski, Shimon (Haifa U. ; Technion)
We compute the one-loop correction to the CFT data of all double-trace operators $[ϕϕ]_{n,\ell}$ for a $Φ^4$ theory in AdS$_3$, for arbitrary values of $n$, $\ell$, and of the scaling dimension $Δ_ϕ>1$. [...]

Stochastic Dynamics of Heavy Quarks in Strongly Coupled Plasma / Rajagopal, Krishna (MIT) ; Scheihing-Hitschfeld, Bruno (UC, Santa Barbara (main)) ; Wiedemann, Urs Achim (CERN)
We study the stochastic dynamics of heavy quarks propagating through the strongly coupled plasma of $\mathcal{N}=4$ supersymmetric Yang-Mills (SYM) theory at nonzero temperature in terms of the corresponding Kolmogorov equation, which correctly describes their kinetic equilibration and the non-Gaussian fluctuations in their momenta without having to restrict their velocity to the non-relativistic regime.

Yoctosecond imaging of the ground state of $^{129}$Xe at the Large Hadron Collider / Giacalone, Giuliano (CERN) ; Nijs, Govert (CERN) ; van der Schee, Wilke (CERN ; Utrecht U. ; NIKHEF, Amsterdam)
Imaging a quantum many-body system requires probes that resolve the coordinates of its constituents in sufficiently large event samples, allowing measurements of correlation functions [1-4]. [...]

The decay rate of metastable cosmic strings beyond the thin-string approximation / Domcke, Valerie (CERN) ; Hamada, Yu (Osaka U.)
In the context of grand unified theories, any cosmic strings present in the post-inflationary universe are likely to be metastable, with a decay rate set by the spontaneous creation of monopole pairs on the string. [...]

The STAR experiment has recently reported data on the $\sqrt{\langleΔp_{T,i}Δp_{T,j}\rangle}/\langle\langle p_T\rangle\rangle$ charged hadron correlation in Au+Au reactions from $\sqrt{s_{NN}}=3-200$ GeV. [...]
